B vitamins (funtional bood profile)

Body levels of B vitamin levels are best determined using enzyme dependent activity tests. Direct measurements of the vitamins are affected by dietary intake and nutritional supplementation.

In our tests for vitamins B1, B2 and B6 we measure the change in enzyme activity (erythrocyte transketolase[ETK], glutathione reductase [EGR] and glutamic-oxalocetic transaminase [EGOT] respectively) before and after the addition of excess vitamin.
